Patent number: 8886745Abstract: Embodiments relate to systems and methods for delivering auxiliary data to a wireless or other device. Content, such as audio, video or textual content, can be hosted by a server for delivery to the device. The content can have associated resources, for example icons, barkers, intros, and outros that are associated with television programming or other media content. A metadata document can describe the set of resources or other auxiliary data associated with a service, channel or content by indicating a resource descriptor, and a URL or other associated resource locator information. The metadata document can be encoded in XML or other formats. The device can locate resources that are intended to be delivered with selected content, since links to the resources are integrated in the metadata document. From the resource descriptor, the device can also identify how a particular resource should be utilized for the service, channel or content.Type: GrantFiled: April 6, 2009Date of Patent: November 11, 2014Assignee: QUALCOMM IncorporatedInventors: Prasanna Kannan, Carlos Marcelo Dias Pazos, An Mei Chen, Sajith Balraj
